Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine. Method for evaluating the motor activity of animal hind limbs after receiving a spinal injury using the swimming test is performed by measuring changes in angular values with a fixed axis in the hip, knee and ankle joints. Before swimming test, each animal's hind extremities are marked with points arranged to mark each bending angle. Then video filming is performed, computer processing of video files is performed and variance of random value of each of flexion angles is calculated for one rowing cycle. If the value of the dispersion ratio is from 2100 to 2765.73 (degree 2 ), the degree of recovery of the motor activity of the hind limb is considered to be the norm, with the value of the dispersion index from 0 to 700 (degree 2 ), the degree of motor activity recovery is considered to be low, if the value of the dispersion index is from 700 to 1400 (degree 2 ), the degree of motor activity recovery is considered to be average; if the dispersion index is from 1400 to 2100 (degree 2 ), the degree of recovery of motor activity is considered to be high. 
     EFFECT: technical result of the invention is higher accuracy of determining motor activity of animal's hind extremities.

A linear incision of the skin of the back along the line of the spinous processes provides surgical access to the posterior elements of the affected spine. The spine is stabilized with a transpedicular structure and the posterior elements of the tumor-affected vertebra are removed, during which the nerve roots are left intact. Then, from the front, under the control of an endoscope passed through the port installed in the projection of the affected vertebra, the anterior part of the affected spine is resected. An implant is placed in the formed post-resection defect.EFFECT: method ensures the removal of the anterior part of the vertebra from the posterior approach without damaging the nerve roots on both sides at the level of the removed vertebra and two adjacent segments, increasing treatment efficiency due to minimally invasive removal of the anterior part of the vertebra.1 cl, 1 ex

Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to the field of electrical engineering and electric power engineering and can be used for determination of damage point in three-phase power transmission line (PTL) of high and ultrahigh voltage. Phase voltages are measured at each end of the line, emergency signals are selected and a kurtosis coefficient of the selected alarm signal is calculated inside the sliding time window. Calculated kurtosis coefficient is compared with the threshold value. Satellite navigation system is used to record the single time value at the moment of exceeding the threshold, transmitting the fixed time value to the remote end of the PTL and distance to point of damage is calculated from difference of single time values fixed at line ends. Alarm signals are selected from differences of measured phase voltages. Transmission and calculations are blocked in the absence of a relay operation triggering signal of the corresponding PTL for disconnection. 
     EFFECT: higher reliability and accuracy of determining point of damage on PTL, simplified implementation of the method.
